On the Physical Meaning of the Geometric Factor and the Effective Thickness in the Montgomery Method
F. S. Oliveira, L. M. S. Alves, M. S. da Luz +2
Simulations carried out with COMSOL software in order to study the electrical resistivity of rectangular samples are reported. The comparison of the results with the four-probe met…
Global room-temperature superconductivity in graphite
Y. V. Kopelevich, J. H. S. Torres, R. Ricardo da Silva +3
Room temperature superconductivity under normal conditions has been a major challenge of physics and material science since its very discovery. Here we report the global room-tempe…
A Simple and Precise Way to Determine Electrical Resistivity of Isotropic Conductors: Simplifying the Four-Probe Method
L. M. S. Alves, F. S. Oliveira, E. C. Romão +2
COMSOL Multiphysics software is used to describe the behavior of the electrical resistivity of several samples with rectangular shape typically used in the Montgomery method. The s…
On the Fermi gas, the Sommerfeld fine structure constant, and the electron-electron scattering in conductors
C. A. M. dos Santos, M. S. da Luz, F. S. Oliveira +1
Electrical energy is considered as a fundamental parameter for inclusion in Fermi gas theory, in addition to thermal energy. It is argued that electrical energy can move some elect…
On the Order Parameter of the Continuous Phase Transition in the Classical and Quantum Mechanical limits
C. A. M. dos Santos, F. S. Oliveira, M. S. da Luz +1
The mean field theory is revisited in the classical and quantum mechanical limits. Taking into account the boundary conditions at the phase transition and the third law of the ther…
